IPC: G03H1/08

Abstract: 1,258,437. X-Ray holography; acoustic holography. DEVENCO Inc. 26 June, 1969, No. 32257/69. Headings H4D and H5R. [Also in Division G2] Holograms are formed by determining the intensity of a plurality of points of an object in a hologram plane by vectorially summing coherent signals, representative of the points on the object but not emanating from the object, with a coherent reference signal disposed at an arbitrary location with respect to the object, a separate summation being carried out for each object point, and recording the magnitude of each resultant signal on a medium which modulates visible light to produce points on the medium corresponding to the object points in the hologram plane. In one embodiment, a plurality of signal voltages V 1 -V m , one allocated for each object point, are fed into respective path attenuators A 1 -A m  and phase shift means F 1 -F m  to process the signal corresponding to that which would occur between a real object and hologram plane. All signals are then vectorially summed together with a reference signal 18 which has been given phase shift 17 to represent an oblique angle of incidence to the hologram plane. The resultant signal H representative of all the points is fed to an oscillograph 20 which presents a visual picture of points S 1 -S m  which can be photographed. Alternatively, the signal voltages V 1 -V m  may represent one object point and further sets of signal voltages 15, 16 represent the other points it is desired to record. The signal voltages may represent a two-dimensional or a three-dimensional array. In a two-dimensional array (Fig. 4) a series of tomographs 50a, 50b are separately illuminated by a source 52. A bank of photocells 54 picks up the appropriate signals and activates signal propagators 58 at the corresponding intensity. The coherent signals from 58, together with a reference signal 60, are received by a scanner which scans a sensing plane 62. The information for each tomograph is stored, e.g. on magnetic tape and then converted into a visual image. The plane of propagators 58 is adjusted with respect to sensing plane 62 a distance corresponding to the spacing between adjacent tomographs, for each record. The signals used may be light, X-rays, sonic waves, radar frequencies, microwaves. There may be derived from data representing an object, e.g. X-ray tomographs, sonograms, radar data, radio-active tracer data, contour map data or analogue or digital data which may be fed to a computer.

Abstract: 1,258,986. Axial-flow compressors; turbines. E. KRZYSZCZUK. Sept.4, 1969, No. 43866/69. Headings F1C and F1T. A turbine or, as shown, an air compressor comprises a casing 12, Fig. 2, having one or more inlets 19 at one end and an outlet 20 at the other end, and a rotor 13 provided with fluid-engaging lobes 24. The lobes extend from end-to-end of the rotor and each has a relatively steep forward wall surface 25 and a gradually sloping rear wall surface 26. In Fig. 2 the lobes are helical and are inclined by an angle of between 30 and 90 degrees to oppositely-pitched helical guide ribs 21 on the casing. During operation the velocity of the air relative to the rotor is successively increased as it flows through Venturi-like passages defined between the lobe crests 27 and the ribs 21, to diffusion spaces defined between the surfaces 26 and the casing. The diffusion angle defined between a surface 26 and the internal surface of the casing in a plane transverse to the respective lobe is between 5 and 20 degrees. Heat insulating discs 36 may be provided in the rotor. In an alternative embodiment, Figs. 4 and 5 (not shown), the lobes (24<SP>1</SP>) are straight and parallel to the rotor axis, and the rotor carries a helical guide rib (21<SP>1</SP>), whereas the casing has a number of shallow helical guide grooves (41) and a series of stationary diffuser vanes (47) at the discharge end of the rotor. Moreover, the rotor has axial bores (40<SP>1</SP>) therethrough for the passage of cooling air.

Abstract: 1,265,767. Projectile fuzes. HONEYWELL Inc. 11 June, 1970 [20 June, 1969], No. 28243/70. Heading F3A. A detonation inhibiting barrier for use in a fuze fitted to a spinning projectile, comprises a container 20 filled with a liquid 22 containing a lower density fluid bubble 23 and having an interior configuration such that the bubble can only occupy a central position in the container when the fuze is spun in use, in which position the bubble offers insufficient resistance compared with that afforded by the liquid for inhibiting the explosive force from a detonator 12. The interior configuration of the container includes an annular restriction 24 through which the bubble must be forced by centrifugal force to occupy a central position. The liquid 22 may be mercury and the bubble 23 may be air or an immiscible liquid. A centrifugal arming arrangement (not shown) can be used to move the detonator 12 into a position where it can be struck by a firing pin 9 only after the projectile has been launched. When the projectile reaches its target, a probe 6 shears off a retaining flange 10 of the firing pin and drives the pin into the detonator.
